Congratulations, the GUI/design looks really beautiful - I honestly *cough* think it looks better than the macOS version, which is something I never thought I'd say about a Windows program. I can potentially see this outselling its macOS sibling.

It's nice to see sharp text (I'm using a Quad HD Dell XPS) although the dropdown menu arrows and template file images are still pixelated (I'm not complaining this is still a beta and the visual brush up probably comes near the end).

A couple of other things, which you are probably aware of: the default text size on new files in the Editor reverts to 100% even if you set it to, say, 120% in settings, and the sidebar button doesn't toggle open and closed (you have to use the dropdown selection, or the keyboard shortcut, which is a lot slower).

I can't wait to use this once its out of beta (in conjunction with the macOS and iOS apps)! It's a really great job all round, and refreshing to see something looking as good as a macOS app on Windows.

I haven't had time to really poke yet, with Thanksgiving and all, but it's generally been pretty smooth. I do wish that the tutorial showed which icons you're looking for, since I don't know the new ones, yet, but it's kind of a picky detail. The 3.0 beta seems to be smoother than the 1.0 beta.
